Acacia courtii is a tall shrub or spreading, weeping tree growing 7-20 m high with pale yellow or cream flower spikes (Tindale & Herscovitch 1990; Harden 1991; Tame 1992; Orchard & Wilson 2001a).

This species has a very restricted distribution and is found only in three general localities in coastal ranges in the Laurieton/Kendall/Kew area of the mid North Coast of NSW (Tame 1992; Quinn et al. 1995; Orchard & Wilson 2001a). It is found in Kerewong SF; at North Brother Mt (including in Camden Haven SF); and at Middle Brother Mt (including in Middle Brother SF) (Tindale & Herscovitch 1990; Harden 1991; Quinn et al. 1995). Six populations were reported by Quinn et al. (1995) and Richards (1999).

In 1996 this taxon had not been recorded within any conservation reserve (Briggs & Leigh 1996).

Details of population sizes, threats and demography are provided in Richards (1999).

Population localities as in Quinn et al. (1995):

  • 'H Knob', Kerewong SF.
  • Captain Cook Bicentenary Rd, North Brother Mt, 27 km SW of Port Macquarie, last surveyed 16/11/1978.
  • Captain Cook Bicentenary Rd, near Camden Haven SF, last surveyed 26/01/1981.
  • Captain Cook Bicentenary Rd near turnoff, North Brother Mt, Laurieton, freehold private property. Last surveyed 20/09/1990, less than 20 plants seen along the road.
  • Middle Brother SF, Middle Brother SF, last surveyed 25/01/1981.
  • Devils Hole, Middle Brother Mt, Middle Brother SF, last surveyed 27/04/1978.

  • This species occurs in dry sclerophyll eucalypt forest and woodland supporting White Mahogany and Grey Gum (Tindale & Herscovitch 1990; Harden 1991; Tame 1992; Orchard & Wilson 2001a). The species occurs principally on steep rocky hillsides composed of microgranite, that are NW to W facing at 40-300 m asl (Tindale & Herscovitch 1990; Tame 1992; Orchard & Wilson 2001a). The soils are shallow stony loams and clays (Tindale & Herscovitch 1990; Harden 1991; Tame 1992).

    Associated species include Allocasuarina torulosa, Eucalyptus acmenoides, E. gummifera, E. intermedia, E. pilularis, E. propinqua, E. siderophloia, E. umbra, Helichrysum elatum, Imperata cylindrica, Lomandra longifolia, Syncarpia glomulifera and Themeda australis (Quinn et al. 1995).

    Flower spikes are borne Nov.-Jan. (Tindale & Herscovitch 1990; Harden 1991; Tame 1992; Orchard & Wilson 2001a) and other times throughout the year (Tame 1992). Fruits probably take about a year to mature (Tindale & Herscovitch 1990), maturing during Nov. (Orchard & Wilson 2001a). This species would be expected to regenerate from seed following fire, as with with other acacias (Quinn et al. 1995).

    The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
